•  Open or short circuit in 4WD CM internal circuit

•  AT (15A) fuse malfunction

•  4WD CM malfunction

•  Poor connection of connectors (female terminals)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT 4WD SOLENOID CONDITION • Switch the ignition to OFF. • Disconnect 4WD solenoid connector. • Inspect 4WD solenoid. (See 4WD SOLENOID INSPECTION.) • Is 4WD solenoid normal?	Yes	Go to next step.
1		No	Replace 4WD solenoid, then go to Step 8.
2	INSPECT 4WD SOLENOID TO 4WD CM (POWER SUPPLY CIRCUIT) FOR OPEN CIRCUIT • Disconnect 4WD CM connector. • Inspect for continuity between 4WD CM terminal O and 4WD solenoid terminal A. • Is there continuity?	Yes	Go to next step.
2		No	Repair or replace harness for open circuit between 4WD CM and 4WD solenoid, then go to Step 8.
3	INSPECT 4WD SOLENOID TO 4WD CM (POWER SUPPLY CIRCUIT) FOR SHORT TO GROUND • Inspect for continuity between 4WD CM terminal O and ground. • Is there continuity?	Yes	Repair or replace harness for short to ground between 4WD CM and 4WD solenoid, then go to Step 8.
3		No	Go to next step.
4	INSPECT 4WD SOLENOID TO 4WD CM (GROUND CIRCUIT) FOR OPEN CIRCUIT • Inspect for continuity between 4WD CM terminal P and 4WD solenoid terminal B. • Is there continuity?	Yes	Go to next step.
4		No	Repair or replace harness for open circuit between 4WD CM and 4WD solenoid, then go to Step 8.
5	INSPECT 4WD SOLENOID TO 4WD CM (GROUND CIRCUIT) FOR SHORT TO GROUND • Inspect for continuity between 4WD CM terminal P and ground. • Is there continuity?	Yes	Repair or replace harness for short to ground between 4WD CM and 4WD solenoid, then go to Step 8.
5		No	Go to next step.
6	INSPECT 4WD CM POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Measure voltage between 4WD CM terminal K and ground. • Is voltage B+?	Yes	Replace 4WD CM, then go to Step 9. (See 4WD CONTROL MODULE REMOVAL/INSTALLATION.)
6		No	Go to next step.
7	INSPECT FUSE CONDITION • Turn ignition key to OFF. • Is AT (15A) fuse normal?	Yes	Repair or replace harness for open circuit between battery and 4WD CM, then go to next step.
7		No	Replace fuse, then go to next step.
8	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory. (See ELECTRONIC 4WD CONTROL SYSTEM ON-BOARD DIAGNOSIS.) • Drive vehicle. • Is the same DTC present?	Yes	Replace 4WD CM, then go to next step. (See 4WD CONTROL MODULE REMOVAL/INSTALLATION.)
8		No	Go to next step.
9	VERIFY AFTER REPAIR PROCEDURE • Is there any other DTC present?	Yes	Go to applicable DTC inspection.
9		No	Troubleshooting completed.
